Dear Music Lover, 
I wanted to personally thank you for your purchase of my Leto Preamp. 
I have loved music all my life – as a musician, record producer and audio engineer. That makes me fussy about sound. 

That’s a good thing. 
Each unit is built by hand with precision and pride to produce the most enjoyable listening experience for you. 
I am proud to put my name on it and honored to share this with you. 
Wishing you many happy years of listening! 
Sincerely, 
-- George Counnas, President of Zesto Audio
